Subject Parsing method name from MemoryBuffer ...?
Date Thu, 17 Sep 2015 19:29:59 GMT
Hi,

I am trying to use Thrift over Xmpp chat. The code example is in java.
Consider the example thrift.

service Api
     {
         string hello(1: string message),
         string hello2(1: string message, 2: string message2),
     }

While calling, i am using memory buffer to use xmpp tarnsport

     transport_in = new TMemoryBuffer(0);
     transport_out = new TMemoryBuffer(0);
     protocol_in = new TJSONProtocol(transport_in);
     protocol_out = new TJSONProtocol(transport_out);

     Message msg = new Message();

     client = new Api.Client(protocol_in, protocol_out);
     client.send_hello("Hello");
     msg.setBody(transport_out.toString("UTF-8"));
     newChat.sendMessage(msg);

Response comes in Xmpp message reply :

     public void processMessage(Chat chat, Message message)
     {
         try
         {
client.getInputProtocol().getTransport().write(message.getBody().getBytes());
             System.out.println("Received message: " + client.recv_hello());
         }
         catch (Exception ex)
         {
Logger.getLogger(SimpleXmppMessage.class.getName()).log(Level.INFO, 
null, ex);
         }
     }

Is there a way to make out the method name for which response is 
received ? Something like

     switch(message.getBody().getBytes()..(method_id))
     {
         case hello:
             process_hello(message.getBody().getBytes());
             break;
         case hello2:
             process_hello2(message.getBody().getBytes());
             break;
     }

One solution can be to maintain maintain a hashmap of message_id in xmpp 
vs thrift RPC method.
However, if it can be handled in thrift payload, it would make solution 
elegant. Any pointers?

Regards.
